Mayumi Osaka is the mother of Naru Osaka.



In episode 23, she showed Naru a rare crystal that had a silvery shine, which Naru mistook for the Silver Crystal and later stole in order to give to Nephrite in his guise as Masato Sanjouin. She also appeared in episode 43, in which she and her daughter were attacked by Oniwabandana, and again in episode 47, when Naru was attacked by the Cardian Vampir.



  • In the DiC English dub of the anime, Mayumi's name is changed to Susan Baker.
  • In the video game Sailor Moon: Another Story, she and Naru were attacked at the beginning of the game by Cenicienta, but were saved by Sailor Moon. She expressed her gratitude and spent the rest of the game as the clerk at Osa-P, selling various items.
